Question: Why my SHARE2U or CAM300 is detecting 1920×1080 and 1280×720 when I plug two USB cameras?

Answer: The devices will always capture at 1920×1080 if only one camera is connected. If there are two, the device will capture from a camera at 1080p and the other at 720p in order to accommodate for video fluidity. This is a hardware limitation of the devices.
